I'm considering ways to make a Storm sorcerer air genasi a little crazy.
It's still a bit of a blank slate concept, I looked first at what I think would be a fun mechanically to play and settled on storm sorcerer air genasi. Just feels like that enhances the storm sorcerer's toolkit nicely.
I've not fully decided on gender yet, though am leaning towards a woman. I was thinking someone initially human who became an air genasi after being struck by lightning three times in one day. (first time unharmed, second time killed, third time revived as an air genasi.)
I haven't decided yet if they already where a sorcerer before then, knowing some magic but not aware of their own sorcerous origin yet.
But I wouldn't want them to feel like some sort of super hero, and I'd certainly want to make them very different from Storm, or other well known lightning/storm wielders.
So I'm considering that being hit by lightning several times in a day could have left them a little crazy. Not insane, I do intend them to be a functional party member. But certainly one with some quirks. The kind which won't get tiresome after a few sessions.
One possibility I am toying with is them misremembering who they where before struck by lightning. Like they are 100% convinced of it. I'd write the background they believe they have, I'd tell the DM it's not true, and they'd get to come up with what it actually is.
Though I'd need an interesting fake background for that which could lead to fun roleplay without getting tiresome.
I am open to other suggestions and thoughts though, about how they could be a bit crazy.
Another thing I am considering is rolling a dice every time they wake up to see if they're in a positive or negative mood, their mood being changeable as the weather but still within reason. Like roll a D20 for it, 1-10 is negative and 11-20 is positive. With a 1 putting them in a really foul mood and a 20 in a super good mood. But in the 2-19 range it would be more subtle. More like them approaching what happens during the day with a glass half full or glass half empty vibe.
